Rock 'n' roll legend Chuck Berry has raised concerns for his health after he pulled out of two sold-out concerts in Spain over the weekend, without explanation.

Berry was scheduled to perform in Estepona on Spain's Mediterranean coast on Saturday and in the northern city of Leon on Sunday, but his agent called to say he couldn't perform, just one hour before the Estepona show, and that Berry had already left Spain.

According to the British newspaper Daily Mail, an unnamed source close to the entertainer in Paris says ill health may have been the cause.

"There were rumours that he's not been feeling well during his current tour, and suffered pain on stage at a concert. We are not sure of Chuck's exact whereabouts at the moment," the source said.

Chuck Berry, the inspiration for countless rock 'n' roll artists including the Beatles, will be 82 in October.
